Interesting (I've only watched the first video so far). I'm kind of sitting on the fence when it comes to the whole climate change thing. Like, I wouldn't be surprised if the climate really was changing because of all the things we do (my carbon footprint happens to be pretty small anyway), and I wouldn't be surprised if it was just another big lie.
I did plan on doing more research, especially after reading this article, but I'm way too swamped right now, so feel free to post any (sourced) material you think I should take a look at ;)
